Title
Bluetooth: bnep: fix wild-memory-access in proto_unregister
Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: bnep: fix wild-memory-access in proto_unregister
There's issue as follows:
KASAN: maybe wild-memory-access in range [0xdead...108-0xdead...10f]
CPU: 3 UID: 0 PID: 2805 Comm: rmmod Tainted: G W
RIP: 0010:proto_unregister+0xee/0x400
Call Trace:
<TASK>
__do_sys_delete_module+0x318/0x580
do_syscall_64+0xc1/0x1d0
entry_SYSCALL_64_after_hwframe+0x77/0x7f
As bnep_init() ignore bnep_sock_init()'s return value, and bnep_sock_init()
will cleanup all resource. Then when remove bnep module will call
bnep_sock_cleanup() to cleanup sock's resource.
To solve above issue just return bnep_sock_init()'s return value in
bnep_exit().

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
